          Abstract

          Background

          Low and middle income countries face many challenges in meeting mental health needs in their regions. Treatment of patients with mental disorders is inadequate in most of these countries and majority of individuals with severe mental disorders remain untreated. The bad news is that mental health problems in these countries are on the rise due to socioeconomic challenges being faced. Regardless of guidelines and directives provided by WHO for organizing mental health services, these countries continue to face many challenges in the effort to cater for mental health needs. Such challenges include lack of human resource for mental health especially at primary health care level, inadequate training of human resource for mental health, misplacement of human resource for mental health, lack of drugs, wrong priorities, problematic insurance coverage for mental disorders, and stigma. This study aimed at exploring mental health care and delivery system at Temeke district hospital, and how services were organized to meet the increasing mental health needs of its population.

          Methods

          A qualitative study was conducted at Temeke hospital in Dar es Salaam, involving 7 in-depth interviews with mental health care providers, 7 in-depth interviews with mentally ill patients, and 2 focus group discussions with caregivers. A convenient sampling procedure was used to select participants for the study. All interviews were audio-recorded in Kiswahili and transcribed. A qualitative Content Analysis was used to analyze data after translation with the aid of Nvivo 10 software.

          Results

          Three main themes were identified. These were resource challenges, environmental/system challenges, and satisfaction with mental health services. Temeke health facility faced resource and environmental/system challenges, and there were mixed feelings on satisfaction with services. Funding and priority issues were found to mainly affect delivery of appropriate services to clients.

          Conclusion

          Health facilities that provide mental health services in the community need to be well equipped with necessary resources to meet the vast needs of people they serve. Having a political will, improving the health systems governance for mental health, and priority setting, are necessary to address the challenges experienced in the delivery of mental health services.

            Mental health in low- and middle-income countries.

            Mental disorders in low- and middle-income countries (LAMIC) do not attract global health policy attention. This article is based on a selective review of research on mental disorders in adults in LAMIC since 2001 and recent analyses of disease burden in developing countries. Mental disorders account for 11.1% of the total burden of disease in LAMIC. Unipolar depressive disorder is the single leading neuropsychiatric cause of disease burden. Alcohol use disorders account for nearly 4% of the attributable disease burden in LAMIC. Mental disorders are closely associated with other public health concerns such as maternal and child health and HIV/AIDS. Poverty, low education, social exclusion, gender disadvantage, conflict and disasters are the major social determinants of mental disorders. Clinical trials demonstrate that locally available, affordable interventions in community and primary care settings are effective for the management of mental disorders. Mental health resources are very scarce and investment in mental health is < 1% of the health budget in many countries. The majority of people with mental disorders do not receive evidence-based care, leading to chronicity, suffering and increased costs of care. Strengthening care and services for people with mental disorders is a priority; this will need additional investment in human resources and piggy backing on existing public health programmes. Campaigns to increase mental health literacy are needed at all levels of the health system.

              Improving access to psychological treatments: Lessons from developing countries

              The global ‘treatment gap’ for psychological treatments The central role played by evidence based psychological treatments (PTs) in the management of mental illnesses is firmly established; in the global context, this importance has been reflected in the inclusion of a number of PTs for mental disorders in the recent WHO guidelines for the treatment of eight mental, neurological and substance use disorders in primary care settings (World Health Organisation, 2010). A rapidly growing evidence testifies to the large burden and adverse impact of mental illness in the global context and the efficacy and cost-effectiveness of specific treatments and delivery systems in low resource settings (Patel et al., 2007; Patel & Thornicroft, 2009). However, the reality is that the vast majority of persons living in such settings, most of which are in low and middle income countries (LMIC), do not have access to these treatments. A central concern of the field of global mental health is addressing this massive ‘treatment gap’, a term which is analogous to the concept of ‘coverage’ in public health, and which routinely exceeds 75% in most parts of the world (Kohn, Saxena, Levav, & Saraceno, 2004). The challenges to implementing evidence-based PTs are enormous: several barriers have been identified ranging from inadequate investments in mental health care to stigma associated with mental illness (Saraceno et al., 2007). In this article, we focus on two barriers which we consider of critical importance in improving access to evidence-based PTs in low resource settings, viz. the lack of skilled human resources and the cultural acceptability and appropriateness of PTs (all of which have been developed in high-income countries (HIC) in different cultural contexts). We have based our observations on the experiences of three randomized controlled trials from three LMIC in Africa and Asia which sought to improve access to the WHO approved PTs for depression, viz., cognitive behaviour therapy-based (CBT-based) or interpersonal psychotherapy (IPT) (World Health Organisation, 2010). The authors of this article are lead investigators of these three trials. The trials The characteristics of the three trials have been described in Table 1. The trials were carried out in rural community settings in Pakistan (the Thinking Health project or THP) and Uganda (the Group Interpersonal Psychotherapy for Uganda or IPT-GU) and in a mixed rural-urban primary care facility setting in India (the MANAS project). Although no precise estimates exist for lack of access to PTs in these settings, our experiences in the settings we describe in this paper would suggest that this may even exceed 90% of persons with depression. All three trials have published their primary results (Bolton et al., 2003; Patel et al., 2010b; Rahman, Malik, Sikander, Roberts, & Creed, 2008) as well as the methods to adapt the PT for the local context (Chatterjee et al., 2008; Rahman, 2007; Verdeli et al., 2004). The three trials are relatively large, with one being the largest ever trial for any mental disorder in a LMIC (Patel et al., 2010b) while another is the largest trial for maternal depression in LMIC (Rahman et al., 2008). Two trials evaluated the PT in a community setting, one of which was in group format (IPT) and one in individual format (CBT-based). The facility based trial had two PTs, one which was non-specific (psychoeducation) and one which was structured (IPT) and these were delivered in a collaborative stepped care format which included antidepressants. All three trials showed impressive benefits on improving recovery rates for depression, as well as on a variety of secondary outcomes (not shown in the Table, but reported in the primary publications). We now turn to the experiences of the three projects in addressing the two major barriers to improving access to PTs. Addressing the shortage of human resources The grave shortage of mental health professionals in LMIC and the inequities between and within nations in the availability and distribution of these resources has been well-documented(Saxena, Thornicroft, Knapp, & Whiteford, 2007). Put bluntly, relying on mental health professionals to deliver PTs will only address a tiny fraction of the treatment gap and task-shifting these interventions to more available and affordable members of the health workforce or community is widely acknowledged to be the only sustainable way of addressing this barrier (Patel, 2009; Patel et al., 2010a). Table 2 describes the types of human resources who delivered the PT in each of the three trials, their training and the supervisory arrangements. Several observations can be made from these findings. First, young women were the preferred therapists for two trials; in the third, therapist gender was matched for gender-specific groups, and most therapists were young adults. Second, none of the therapists had any prior training in mental health; in two trials, the therapist was a lay person from the community who had no health background at all. Third, the period of didactics varied but was, in general, relatively short, and focused on skills rather than theory and mostly involved participatory methods; the longest period (for the Goa trial) was due to the need to train the therapists in the overall collaborative care model and the actual PT focused session itself was for three weeks. Fourth, all the projects included a well-defined, structured supervisory protocol by a skilled mental health professional who played a variety of supervisory roles from case record reviews and, case discussions to joint case consultations. In summary, all three projects showed that people with no mental health background (or even no health background at all) and with relatively short training and continuing supervision could deliver the PT effectively. Addressing the acceptability and cultural appropriateness of ‘western’ psychological treatments The cross-cultural applicability of PTs, all of which have been principally developed and evaluated in ‘western’ cultural contexts, to LMIC has been questioned by some authors (Tseng, April 2004). It is widely accepted that, just as with the classification and measurement of mental illnesses, mental health interventions also need cross-cultural adaptation to ensure the acceptability and appropriateness to the particular context (Patel, 2000). All three projects adopted systematic methodologies to address this barrier, approximating the steps of the Medical Research Council (UK) guidelines for the development of ‘complex’ interventions (Craig et al., 2008). In MANAS, the adaptation of the PT was part of the overall adaptation of all the components of the collaborative stepped care intervention and involved three distinct phases over 14 months: consultation with stakeholders involving 14 meetings with local, national and international stakeholders from the public, private and academic sectors to explore the feasibility of the proposed intervention; formative research with people affected by depression and health care providers in four public and four private primary health care facilities with quantitative process indicator data and qualitative data through in-depth interviews with doctors, facility staff, health counsellors and patients collected to explore feasibility and acceptability of specific components of the intervention; and piloting of the intervention in four primary health care centres involving interviews with 77 patients to explore their experiences of the intervention and reasons for non-adherence(Chatterjee et al., 2008). In the THP, the intervention was developed over a period of 12 months through: consultations with key stakeholders including in-depth interviews with 30 depressed mothers, four focus groups with purposively sampled 24 Lady Health Workers, and key-informant interviews with six primary care staff; and examination of data from an epidemiological study in which the investigators had explored psychosocial risk factors for perinatal depression in the same community (Rahman, 2007).In the IPT-GU, an initial draft of the adapted protocol was developed over four weeks based on data from an ethnographic study of depression in the region, input from researchers and, clinicians identified as site supervisors for the trial, and dialogue with local community leaders. This working document was modified substantially during the 10-day group facilitator training, based on the trainees’ feedback about whether and how each strategy and technique needed to be modified to fit the local culture (Verdeli et al., 2004). Further piloting was carried out to assess therapist competence. Thus, in all three cases, the development of the intervention involved multiple steps and mixed methods with a heavy reliance on qualitative methods. Data synthesis involved triangulation of these mixed methods derived data and theories to obtain an in-depth understanding of the issues likely to affect the feasibility, acceptability, effectiveness and sustainability of the intervention. This systematic process demonstrated that most of the broad procedures and techniques of both IPT and CBT were cross-culturally applicable (Table 3). However, there were some very important modifications which were needed to improve the acceptability of the PT and enhance the feasibility of its use by non-specialist therapists. These included: ‘simplifying’ the language and content by removing the jargon associated with them; using pictorial materials for guiding therapists and patients; avoiding the use of psychiatric labels while recognizing that the symptoms were a reflection of the health consequences of stress or ‘life problems’; using contextually appropriate methods and metaphors to communicate the techniques and procedures associated with the PT such as using religious idioms; de-emphasizing some components of the PT which were found to be unacceptable or difficult to communicate, for example the domain of ‘interpersonal deficits;; and involving other individuals in the affected person’s social world, in particular, family members. Addressing other barriers to scaling up A major barrier which needs to also be addressed, alongside increasing the availability and affordability of culturally appropriate PTs, is to enhance the demand for such interventions. Community awareness about depression and its responsiveness to PT, usually culturally appropriate language (as was done in IPT-GU), and pro-active case finding using contextually validated screening tools (as was done in MANAS) offer two specific strategies to address this barrier. Several other barriers were encountered during the development of the interventions (Table 4). Notable barriers were the low acceptability of PTs in contexts where local communities were unfamiliar with the use of ‘talking’ treatments for health problems; the stigma associated with accessing health care for ‘mental’ health problems; the competing work pressures and low motivation for health care workers; and the low adherence often due to the opportunity costs due to time taken to attend sessions and the direct costs of transport to health facilities. Table 4 summarises the key strategies taken by the project teams to address these barriers. Implications for improving access to PT at scale The MANAS, THP and IPT-GU project experiences demonstrated unequivocally that persons with no mental health experience can effectively deliver PTs either in a stand-alone format or as part of a delivery system which includes other treatments, if five key conditions are met: first, that they are recruited from the local community; second, that they are provided with well-designed participatory training based on active learning principles; third, that the PT is suitably modified to address the skill set of such workers and to address contextual issues and barriers; fourth, that supervision is provided by persons with more extensive mental health experience and skills based on structured protocols for supervision, risk management and other aspects of clinical governance; and fifth, that the stigma associated with mental illness is addressed by using contextually appropriate concepts and integrating mental health with routine health care or existing community delivery systems (e.g. microfinance groups). We consider five implications of these findings to improving access to PTs in the global context. First, provided the conditions outlined earlier are met, the potential human resource for delivery of PTs can now be expanded to include virtually any member of the community. In particular, future work could examine the role of volunteers and peers (for example, other persons who have recovered from depression, or mothers for post-natally depressed women) and traditional healers in those settings where they are widely accessed. Second, technological and practical flexibility is essential for the delivery of PTs. Thus strategies such as conducting sessions on the telephone, broadening the settings for PT delivery to include homes and community settings, and tapping into family and community resources enhance opportunities for non-medical interventions to facilitate recovery. Third, the adaptation of PTs can greatly benefit from a systematic methodology to identify and address barriers to acceptability and feasibility. Such a methodology requires participation of representatives of diverse stakeholder groups; adequately designed formative and pilot studies typically utilizing mixed methods; and a systematic review of the literature or qualitative studies on cultural expressions of distress and incorporating these findings in the proposed intervention. We are currently engaged in a new program (PREMIUM http://www.sangath.com/details.php%3fnav_id=123) which seeks to systematically ‘codify’ this methodology. Fourth, such a procedure shows that while some components of PT show universal applicability, others do need considerable adaptation for transferability to this context. Future work needs to define the extent to which such adaptations may influence the original theoretical model which lay at the heart of the PT and the extent to which elements common to many brief structured PTs (for e.g. goal setting, problem solving, improving interpersonal communication, etc) may out-weigh the differences between PTs. It is plausible that these common elements may be the most cost-effective interventions to improve access to PT in low resource contexts. Fifth, we think that much can be learned through sharing of knowledge about improving access in LMIC and HIC. There is a growing evidence base in HIC on improving access to PTs for ethnic minority groups who have traditionally been under-represented in PT services (Miranda et al., 2005). Many of the lessons drawn from those studies mirror the experiences we have described in LMIC and point towards some ‘universal’ truths about adapting PTs across cultures and health systems. Ultimately, scaling up evidence-based PTs in low resource settings will also need to recognize that partnerships with, and commitments from, key stakeholder communities concerned with health care delivery is essential from the outset. Health systems in most LMIC are struggling to cope with great challenges ranging from the rising burden of chronic diseases to scarce resources; in this context, we believe that the inherent nature of PTs, unlike many more ‘medical’ interventions, afford the unique opportunity of a ‘bottom–top’ approach whereby the community could be much more actively involved and ‘empowered’. For this to happen, local and national health care agencies should be involved from the early stages of treatment adaptation and development to engage them in subsequent treatment uptake, not least by recognizing the value of PTs and ensuring appropriate resources for health workers engaged with delivery of PTs. Arguably, however, the biggest barrier to scaling up may be the perception held by mental health specialists about the risks of non-specialist health workers delivering PTs; the trials we have described have shown that using such providers led to acceptable, feasible and effective interventions for depression. Thus, a commitment by the global community of mental health professionals about the safety, effectiveness and necessity for ‘task-shifting’ of PTs to lay and community health providers is a pressing need. Above all, we need to emphasize that the central component of improving access is not simply handing over of the responsibility of delivering PT to less trained persons, but sharing these with a wider group of available human resources so as to ultimately close the ‘psychological treatment gap’ globally.
